“Inflammation-cancer” transformation of chronic atrophic gastritis （CAG） refers to the process in which the gastric mucosa， in the context of CAG， progresses through stages of precancerous lesions of gastric cancer （PLGC）， such as intestinal metaplasia and dysplasia， and eventually develops into gastric cancer （GC）. In China， the incidence and mortality rates of GC rank among the highest in the world， and the proportion of GC cases caused by gastric mucosal infection and inflammation has been increasing. Modern medical treatments for CAG and PLGC mainly rely on drug therapy， endoscopic resection， and regular surveillance. Although these disease management strategies are relatively mature， they present limitations in early lesion prevention and recurrence risk control. Therefore， it is imperative to identify therapeutic approaches for CAG and PLGC that offer preventive， reversible， and recurrence-reducing benefits. With advances in research on the mechanisms underlying inflammation-cancer transformation and the integration of traditional Chinese and Western medicine， the advantages of TCM in preventing and even reversing early-stage CAG and PLGC have gradually become apparent. This review explored the mechanisms of inflammation-cancer transformation in CAG from five aspects： inflammatory microenvironment， autophagy， glycolysis， bile acids， and ferroptosis. In conjunction with TCM theory and a deeper understanding of the distinct mechanisms involved in the inflammation-cancer transformation of CAG， this review further discussed the specific mechanisms through which TCM intervened in treating CAG and PLGC， with the aim of providing theoretical support and therapeutic insights for future clinical applications.

Objective The quantitative analysis model of mifepristone binary mixed crystal system was established by infrared spectroscopy to improve the quality control level of Mifepristone raw material.Methods Two mifepristone polymorphs samples were prepared and characterized,and the quantitative analysis model of infrared spectral data was constructed by classical linear regression method and chemometrics method respectively.On this basis,the influence of different factors on the model quality was investigated comprehensively.Results Infrared spectroscopy combined with classical linear regression method and stoichiometric method can build a quantitative analysis model for binary mifepristone polymorphs system,and the model has good linear regression coefficient(R2)and root mean square error of cross validation(RMSECV)values.Conclusions The two polymorphs of mifepristone have independent infrared spectral characteristic peaks that can be used for quantitative study,so the classical linear regression method has more significant methodical advantages for this system.The chemometrics method is more suitable for the quantitative study of complex mixed polymorphs system.

Objective To study the pharmacokinetics of dihydralazine sulfate,triamterene,hydrochlorothiazide and reserpine in compound reserpine and triamterene in rats.Methods SD rats were randomly divided into three groups.Compound reserpine and triamterene was given at dose of 3.6,10.8 and 32.4 mg·kg-1 by single oral gavage,respectively.HPLC-MS was used to measure the blood concentrations of dihydralazine sulfate,triamterene,hydrochlorothiazide,and reserpine at various time points.DAS software was used to compute the pharmacokinetic parameters.Results After a single oral gavage of 3.6,10.8 and 32.4 mg·kg-1 of compound reserpine tablets triamterene,the tmax of dihydralazine sulfate in rat plasma were 1.50,1.33,and 1.42 h,and the Cmax of dihydralazine sulfate were 12.30,38.31 and 120.52 μg·L-1,respectively.The tmax of triamterene were 1.33,1.33,and 1.42 h,and the Cmax of triamterene were 20.93,67.36,and 168.64 μg·L-1,respectively.The tmax of hydrochlorothiazide were 2.00,2.00,and 1.75 h,and the Cmax of hydrochlorothiazide were 19.89,57.58,and 160.78 μg·L-1,respectively.Risperdal was found at very low levels in rat plasma,and only trace amounts were detected at 1.00 and 1.50 h of 32.4 mg·kg-1 administration.Conclusions Dihydralazine sulfate,triamterene,and hydrochlorothiazide can be eliminated quickly after compound reserpine and triamterene was given orally to rats,and their oral absorption is basically linear.The greater the dosage,the better the absorption of effective components.

Drynaria fortunei,commonly known as"bone setting herb",has been widely included in various traditional Chinese herb-al classics for treating bone injuries.It is used medicinally from its rhizome,which has a bitter taste and warm property.It is known to nourish the kidneys,strengthen bones,and alleviate pain from injuries.The chemical constituents mainly include flavonoids,phenylpro-panoids,triterpenoids,phenolic acids,lignans,and sterols.Modern medical research indicates that Drynaria fortunei has anti-osteoporo-sis effects,promotes fracture healing,has anti-inflammatory properties,and benefits dental health.This article reviews the historical use of Drynaria fortunei and recent research on its chemical composition and pharmacological effects,summarizing some of the mechanisms of action.The aim is to provide a reference for further research on this medicinal herb.

Objective To investigate the effects of amlodipine benzenesulfonate tablets administered at different time points on blood pressure in Mongolian and Han patients with non-dipping hypertension.Methods A total of 68 cases of Mongolian with non-dipping hypertension who had settled in Inner Mongolia and had not intermarried with other nationalities within three generations and 70 cases of Han patients with non-dipping hypertension were consecutively selected as research object,they all received diagnosis at the Second Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology from September 2022 to September 2023,and were divided into two groups on average according to the simple randomization method,the group of medication after dinner(group A)and the group of medication before bedtime(group B),and both groups took irbesartan 75mg in the morning,once a day.After that amlodipine benzenesulfonate tablets 5mg,once a day,were added after dinner in group A and before bedtime in group B.Treatment was carried out for 6 months.The ambulatory blood pressure parameters of total patients,Han patients and Mongolian patients before and after treatment were compared between two groups,as well as the proportion of nonpareil blood pressure and the blood pressure compliance rate of total patients after treatment between two groups.Results ①Dynamic blood pressure indicators:After treatment,the dynamic blood pressure levels in both groups of patients decreased,and the decrease in indicators in group A was more significant than that in group B(P＜0.05);Han and Mongolian patients were compared within their respective populations,and the results were consistent with the inter group comparison of the total patients(P＜0.05).②Correction of non dipper blood pressure:After treatment,the effective rates of dipper blood pressure in group A were higher than those in group B,and the difference was statistically significant(P＜0.05).③Blood pressure compliance rate:The blood pressure compliance rate of group A patients after treatment was higher than that of group B,and the difference was statistically significant(P＜0.05).Conclusion Amlodipine benzenesulfonate taken at different times has certain therapeutic effects on patients with non-dipping hypertension,and therapeutic effects are better compared with the effect of patients taking the drug after dinner,the degree of improvement of ambulatory blood pressure indexes,correction rate of non-dipping hypertension and blood pressure compliance rate are better than those of patients who take the drug before bedtime,and the effect of taking the drug after dinner is better than that take the drug before bedtime for both Mongolian and Han patients with non-dipping hypertension.
